I am not even sure were to begin, my axos have been getting red a lot so i did water changes and the red wont go away. there were bumps that looked maybe like blisters as well as white patches that appear as if they are shedding but the parameters of the tank is fine. i recently made a divider as i had 2 female and 1 male. one of my females have dies and i dont know why. i also recently added black sand i have read that people use sand blasting sand so that is what it is. i have had this tank up and running for almost a year. i recently did a major clean and rearranged things which may have taken away some of the good bacteria. i have also used a lil "Genchem No Planaria 50g Rid of Planaria Hydra Safe For Shrimps And Plants" but that should have been removed with all the water changes i have done. they were in a 40 gal long that has a 40-60 gal filter and another 120 gal filter. the 120 filter was added with the new changes/ cleaning. since my albino female passed :'( i have removed them from the tank completely. I have been using Aquasafe water conditioner in the tank. They are in a 5 gal bucket with “Tetrafauna Aquasafe*Water*Conditioner*For Reptiles And Amphibians” but they are still really red and veiny. I am not sure what to do but I don’t wanna lose them. And I don’t have accuess to a vet.
